All the time with my personal data. You don't even need to install anything. Many applications and websites will do share your data to Facebook. Friends too. It's great.

Wait, I thought we were all paying with our data and the general state of surveillance on the web.

generally by searching Facebook on duckduckgo and following links, for some people it might be preinstalled on their phones so they literally bought it.

in any case it was given willingly to me by Facebook

True enough. I uninstall it from my phone and after every update it magically reappears. Ah Facebook, like U2 in ITunes, will they never learn.
